BOSL BOARD - THE ULTRA LOW POWERED IOT LOGGING DEVICE
This little beauty costs less than an Arduino and Sim5320a put together, yet it comes already assembled, runs on 4v, is ultra low power consuming (we removed all the overheads of the off the shelf arduinos) and can send data via the CAT-M1 or NB-IoT networks! We estimate that these things can log each minute for over 12months!
SIM7000 SIM CARD COMMUNITCATION ISSUE
There has been an issue where some of our boards aren't recognising the SIM cards, and so can't upload any data. To detect is if the issue is present the following AT command sequence can be sent.
| Command | Response |
|---|---|
| AT+CFUN=0 | |
| +CPIN: NOT READY | |
| OK | |
| AT+CFUN=1 | |
| OK | |
| +CPIN = READY | |
| SIM READY |
